Seal Faces:
Carbon Graphite / Silicon Carbide (SiC) / Tungsten Carbide (TC)
SiC/SiC for corrosive/abrasive media; TC/TC for high‑pressure/abrasive service
Secondary Seals: NBR, EPDM, FKM (Viton), FFKM, PTFE
Springs & Metal Parts: 304, 316L, 2205, Hastelloy C‑276
MOR 224 is a standard double‑end, multi‑spring, unbalanced mechanical seal (often referred to as double acting/dual seal) designed for centrifugal pumps, chemical pumps, and process equipment handling hazardous, corrosive, or particle‑laden fluids. It follows ISO 3069, DIN 24960, and GB 6556 standards, offering robust dual‑face sealing with back‑to‑back structure.
Key Features
Double‑End (Dual Face) Structure: Two sets of seal faces arranged back‑to‑back, creating a buffer chamber for barrier fluid.
Multi‑Spring Design: Uniform face loading, excellent shaft run‑out compensation, bidirectional rotation.
Unbalanced Configuration: Simple, cost‑effective for medium‑pressure applications.
Integrated Shaft Sleeve: Protects shaft, simplifies installation, and enhances stability.
Modular & Interchangeable: Direct replacement for EagleBurgmann 224/224UU and equivalent OEM seals.
Applications
Chemical centrifugal pumps (ISO 2858 standard)
Caustic, acid, solvent, and slurry transfer pumps
Wastewater, pulp & paper, and pharmaceutical process pumps
Petrochemical, refining, and food processing equipment
Pumps handling toxic, flammable, or high‑purity fluids
Advantages
Superior Leakage Control: Dual faces prevent hazardous media from escaping; ideal for toxic, flammable, or corrosive fluids.
Barrier Fluid Compatibility: Buffer chamber supports API Plan 52/53/54 for lubrication and cooling.
Robust in Tough Conditions: Handles particles, crystals, fibers, and high‑temperature chemicals.
Long Service Life: Multi‑springs reduce wear; high‑grade materials resist corrosion.
Easy Maintenance: Pre‑assembled cartridge‑style design for quick pump installation.
